Remove ^I, ^L in file

Paola Guizado — Thu, 15 Nov 2007 14:47:34 GMT

Hi.
Please your help.

I have a file and I do want to remove him these symbols ^I, ^L like I make?

Thanks very much.
With the command sed i used this,
sed '$d' file1 > file2
thinking in that the symbol was at the end of the file
but it should not always be this way. it is better than it validates in the whole file.

Hi:

# perl -ple 's%\011%%g;s%\014%%g' file

The ^I is a horizonal tab; The ^L is a formfeed. See the manpages for 'ascii(5)'.

By the way, please evaluate and assign points to the responses to your previous question:

Hi (again):

If you prefer, you could also use the control keys and letters (Ctrl-I and Ctrl-L) to compose a 'sed' substitution:

# sed -e 's/ //g' -e 's/^L//g'

Note that the tab character composed as CTRL-I will appear as whitespace in this post.

You can also use vi

:g/^L/s///

ctrl-l has to be entered with the key strokes:

ctrl-v followed by ctrl-l
